What I loved most about this app is seeing the nutrients your body needs throughout the day which many people miss. Very simple and easy to use. The only downside I see are the limited options for some cuisines, I’m from the Philippines and trying to find Pork blood and chicken intestines as that is a part of our culture. but still the best app i used hands down.
Developer Response
Hi there!Thank you so much for the feedback about what you're loving and where you think we can improve, as our app grows we will hopefully have even better coverage and include foods that you would traditionally find in the Philippines! That said, in the mean time you could create Custom Foods and recipes if you know the nutrition details :) Hope this helps!Have a great day!
Greatest Cal tracking app

Cronometer is by fat the best calorie tracking app ever. What I like about it is you can customize everything as needed. You can also track your micronutrient intake, so you’ll know what you lack if you eat relatively the same meals everyday. Great for people who are serious at getting in shape, also very beginner friendly.
Developer Response
Thanks for the amazing feedback! We’re glad Cronometer gives you the customization and detail you need, from calories and macros to micronutrients. Great to hear it feels useful for serious goals while still being beginner friendly. We really appreciate the support 🧡
I use it everyday

The free version has everything i need compared to the two famous food tracking app. Only downside of this is the limited food data in the library but it is because there are a few users.
Developer Response
Hi there!Great news - we currently have our team working on photo logging! Right now, one of the limitations is the accuracy of photo logging with nutrition trackers, so when we have that dialled to the level our users expect out of us you can be sure that we will release it!Thank you for your feedback and we're hoping you love it when it's released!All the best for a great weekend!

Saw this app recommended on Reddit and can attest that it does everything I could want a calorie counting app to do, and more. I’ve already recommended it to my friends after losing 5kg in 6 weeks by using this app.
